The wide range of bridge types inspected under these contracts included: steel truss, steel cable stay stiffening truss, steel girder, pre-stressed concrete multiple girder, concrete multiple box beam, concrete multiple box culvert underpass, concrete slab, metal culvert, and timber multiple beam.

Using industrial rope access techniques combined with mechanical access equipment, B&N teams provided:

  • 80+ National Bridge Inspection Standards (NBIS) inspections
  • FDOT PONTIS inspection records for structures over state routes
  • Fracture Critical inspections
  • Initial and warranty inspections
  • Instrumentation and testing of bridge components, including cable stays
  • Repair/maintenance recommendations
  • Traffic control design for structures over roadways

Notable structures that were inspected under these contracts included two major truss bridges over I-4 and US 17/92, a two-girder fracture critical system over I-4, and multiple structures over and under the Cross Seminole Trail, Seminole Wekiva Trail, and other pedestrian facilities.
